FAKE VOICES

FYI, Improving Technology, Scams done with fake voices, Voice scam defenses, Voice scam defense articles, Consumer uses of fake voices and AI

Artificial Intelligence allows bad guys to learn someone's voice and vocal patterns and then manipulate it to scam people. Thomas Brewster has said "Once a technology confined to the realm of fictional capers like Mission: Impossible, voice cloning is now widely available." The important thing to always be aware of is: if you get a phone call from someone you know who seems to be in an emergency situation and is pleading for money, it might be a scam with a faked voice.

These scams do not yet have an official name. I have seen it referred to with all these terms:

Voice fraud
Voice phishing or the shortened version: vishing
Voice cloning and Vocal Cloning
Voice swapping
Artificial voice
AI voice cloning and AI-generated audio
Synthetic Audio and Deepfake Audio and Audio Deepfakes
Deep Voice, and the generic, DeepFake
Family-emergency schemes
Impersonation scams

December 3, 2024: Criminals Use Generative Artificial Intelligence to Facilitate Financial Fraud from the FBI. Alert Number: I-120324-PSA. Quoting: "Generative AI reduces the time and effort criminals must expend to deceive their targets. Generative AI takes what it has learned from examples input by a user and synthesizes something entirely new based on that information. These tools assist with content creation and can correct for human errors that might otherwise serve as warning signs of fraud." This has an overview of many different approaches used by bad guys in scams, and, some defensive steps.
April 27, 2023: It's Time to Protect Yourself From AI Voice Scams by Caroline Mimbs Nyce in The Atlantic. Sub-head: Anyone can create a convincing clone of a stranger’s voice. What now? This is a worthwhile read, it takes a measured look at where things currently stand. Quoting: "[voice scams] have existed for some time ... but they’ve gotten better, cheaper, and more accessible in the past several months alongside a generative-AI boom. Now anyone with a dollar, a few minutes, and an Internet connection can synthesize a stranger’s voice."

TD Bank, Chase and Wells Fargo did not respond to a request for comment. Likewise, ElevenLabs did not respond to multiple requests for comment.
January 30, 2023: AI-Generated Voice Firm Clamps Down After 4chan Makes Celebrity Voices for Abuse by Joseph Cox for Vice. 4chan members have used AI software to generate voices that sound like Joe Rogan, Ben Shapiro, and Emma Watson to spew racist material. For example, a fake Emma Watson reads a section of Mein Kampf. ElevenLabs says it can generate a clone of someone’s voice from a clean sample recording, over one minute long. The high quality of the fake voices, and the ease which which people create them, highlight the looming risk of deepfake audio clips.
January 9, 2023. It is bad enough that, when we get a phone call, the callerid can be faked. Now, faking the voice is getting better and easier. Microsoft's new AI can simulate anyone’s voice with 3 seconds of audio by Benj Edwards for Ars Technica. It claimed that this new system can preserve the speaker's emotional tone and acoustic environment. Quoting: "Microsoft researchers announced a new text-to-speech AI model called VALL-E that can closely simulate a person's voice when given a three-second audio sample ... VALL-E can synthesize audio of that person saying anything - and do it in a way that attempts to preserve the speaker's emotional tone. Unlike other text-to-speech methods ... VALL-E generates discrete audio codec codes from text and acoustic prompts. It basically analyzes how a person sounds, breaks that information into discrete components (called 'tokens') thanks to EnCodec, and uses training data to match what it 'knows' about how that voice would sound if it spoke other phrases outside of the three-second sample.".

SCAMS DONE WITH FAKE VOICES top

April 5, 2025: The Panicked Voice on the Phone Sounded Like Her Daughter. It Wasn’t. by Julie Jargon for the Wall Street Journal. Subscription required. A mother gets a phone call from her daughter and the bad guys that abducted her. The mother falls for the scam and loses money. Most interesting aspect of the story is the quote from the mother: "It’s not that it sounded almost like her, It sounded just like her." The technology is good enough to fool a mother about her daughter's voice.
July 27, 2024: Ferrari exec foils deepfake attempt by asking the scammer a question only CEO Benedetto Vigna could answer by Daniele Lepido and Bloomberg for Fortune. A Ferrari executive first got a bunch of unexpected messages, seemingly from the CEO. Then a scam phone call. The voice impersonating the CEO was convincing, but the exec posed a question that only the real CEO would know. End of phone call. Quoting: "While these generative AI tools can create convincing deepfake images, videos and recordings, they’ve not yet proved convincing enough to cause the widespread deception that many have warned about."
July 5, 2024: Fake voice scams have gone Hollywood - they made a movie about it. See: The voice scam call portrayed in 'Thelma' is real and an increasing threat in the age of AI by Genna Contino for CNBC. The focus here is on Senior Citizens who may need extra protection from scams. For that, experts recommend freezing their credit and establishing a financial surrogate.

Password manager LastPass is warning the public to be on guard against AI-generated scam calls pretending to be your boss, after one such deepfake audio call targeted a company employee. The scam failed. It used a WhatsApp audio call and impersonated the LastPass CEO Karim Toubba.
March 7, 2024: From The New Yorker Magazine: The Terrifying A.I. Scam That Uses Your Loved One’s Voice by Charles Bethea. Long article that describes multiple instances of AI generated fake voices of relatives used for scams. On the tech side, it notes that a big breakthrough came in 2022 when: "... ElevenLabs unveiled a service that produced impressive clones of virtually any voice quickly; breathing sounds had been incorporated, and more than two dozen languages could be cloned. ElevenLabs’s technology is now widely available. 'You can just navigate to an app, pay five dollars a month, feed it forty-five seconds of someone's voice, and then clone that voice,' ... The company is now valued at more than a billion dollars, and the rest of Big Tech is chasing closely behind." The Microsoft Vall-E cloning program needs just a 3 second sample to replicate a voice. It is not available to the public. AI generated voices are good enough to eliminate sub-titles and dubbing in movies. It allows actors to appear to speak other languages. "In January, voters in New Hampshire received a robocall call from Joe Biden’s voice telling them not to vote in the primary." As to defense, there is not much here just that wiring money, sending cryptocurrency and buying gift cards are common indicators of a scam. One example in the article used Venmo to pay the bad guys. One family, after being victimized, chose a family password, but someone forgot it.

Another case of a mother being fooled into thinking that the voice on the phone was her daughter. Quoting: "Imposter scams have been around for years. Sometimes, the caller reaches out to grandparents and says their grandchild has been in an accident and needs money. Fake kidnappers have used generic recordings of people screaming. But federal officials warn such schemes are getting more sophisticated, and that some recent ones have one thing in common: cloned voices."
March 5, 2023: They thought loved ones were calling for help. It was an AI scam. by Pranshu Verma for the Washington Post. To fake the voice of a person used to require a large voice sample. No more. Bad guys can now replicate a voice with an audio sample of a few sentences. The audio could come from YouTube, TikTok, Instagram, Facebook videos or podcasts, making many people vulnerable. Or rather, making their relatives vulnerable to scammers. The technology to do this is now much easier to use and cheaper making it available to more scammers.

"Separately, a Click researcher found HSBC Voice ID kept letting them try to access their account after they deliberately failed on 20 separate occasions spread over 12 minutes."

VOICE SCAM DEFENSES top

The first defense is to be aware that this sort of thing exists. Calls to older adults by younger relatives asking for money for an emergency is a well known scam. Likewise, calls from your boss asking you to transfer money to a new bank account are suspicious. Families should have a safe word (or safe phrase) that only they know. This can be used to verify that a voice really belongs to the person it sounds like.

Be aware that the callerid on a phone call can be spoofed.
Be aware that a voice can be cloned using audio clips from social media posts.
Kidnapping scams need to know where the victim is supposed to be to make the scam believable. To counter this, the FBI says to not post information about upcoming trips on social media. Especially don't mention airplane trips because someone on a plane can not be called to verify that they are safe.
When a loved one calls asking for money, put the call on hold and call them back. Or, have someone else call them back. Or call someone who can verify where the supposed victim really is.
Verify the identity of the caller. If it is a kidnapping scam, verify the identity of the kidnapping victim.
1. Ask them a question that only they would know. The problem with this is that if you believe the emergency is real, you may not think clearly.
2. Setup a security phrase or code word with your loved ones to verify identities on a phone call. For example, emergency requests for money or sensitive information should include the term "hockey pucks".
3. October 17, 2023: Should you have a family 'safe word' against AI voice-spoofing scams? by Shira Ovide in the Washington Post. The article offers background on the issue, including the helpful reminder that caller ID can be faked.
Try to keep your personal information away from the bad guys. To that end, do what you can to improve the privacy of your social media, such that your personal info is only visible to the people you want to share it with.
If your credit reports are frozen, it can minimize the damage should you get scammed.

• Varying tone inflection in speech
• Phrasing – would the speaker say it that way?
• Context of message – Is it relevant to a recent discussion or can they answer related questions?
• Contextual clues - are background sounds consistent with the presumed location of the speaker?

There are, however, sharp limits to the viability of that model, so the company has recently been experimenting with AI. Quoting: "Now we can really have conversations with companies and that's dramatically increased our success rate and allowed us to pursue much higher levels of disputes. Now we can negotiate hospital bills, lower utility bills, things where the companies respond and we can chat with them in real time .. That's the future of bureaucracy: bots negotiating with each other..." said Joshua Browder, CEO of DoNotPay.
